A Havoc Missile Launcher is an Imperial Missile Launcher system that was widely used by the Space Marine Legions during the Great Crusade as an additional assault weapon for their vehicles. The weapon is a simple, yet effective multi-barrelled Missile Launcher that can fire clusters of high-explosive munitions. The Havoc Missile Launcher system is believed to be the precursor of the Cyclone Missile Launcher system used by present-day Space Marine Terminators, and possibly also the massive Havoc Missile Rack used on the Banelord-class Titan of the Traitor Titan Legions. Havoc Missile Launchers are no longer in use by most present-day Imperial military forces, which instead use Hunter-Killer Missile Launchers. However, the weapon is still widely used by many Traitor Legions.
